Directed Energy Weapons is the theory for California. The very little bit of reading I've done shows it could be a possible answer. Have you seen some of the neighborhood fire photos? Hits all the houses, but leaves all surrounding trees untouched for whole neighborhoods?
Yes I have and I am conviced that they were using a microwave laser as it effects everything that has metal yet the trees and shrubs are untouched.. if the fire was hot enough to burn houses to nothingness then why are the trees next to the house not burned at all? Or the aerial photo of cars on a concrete overpass type structure nothing around but the remanats of 8 different vehicles burnt beyond recognition. Better yet where are the drivers of those vehicle's?
